1. A method for determining measurement quality of one or more measurements from one or more sensors, comprising:

  • obtaining, at a processor, a first amplification gain for a first signal generated by the one or more sensors, wherein the one or more sensors are positioned on a subject'"'"'s body, and wherein the first amplification gain is for amplifying or reducing the first signal to within a first pre-determined level at a first time;

    determining, at the processor, a second amplification gain for a second signal generated by the one or more sensors, wherein the second amplification gain is for amplifying or reducing the second signal to within a second pre-determined level at a second time after the first time; and

    generating, at the processor, a contact quality value of a contact between the one or more sensors and the subject'"'"'s body based on a degree of change between the first amplification gain and the second amplification gain with respect to time.
